MEASURING DEVICE.

Application filed June 14, 1921. Serial No. 477,514.

of the United States, and a resident of Broken Arrow, in the county ofTulsa and- State of Oklahoma, have invented certain new and usefulImprovements in Measuring Devices; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same. I

This invention relates to improvementsin measuring devices and moreparticularly to such as are adapted to register the amount of stitchingdone by sewing machines-one object of the invention being to providesimple and etficient means which may be readily attached to the head ofa sewing machine and which shall be operable from the driving shafttherein to register. through the .medium of the rotation of said shaftand the number of stitches effected during each rotation. theamount ofstitching accomplished in yards. feet and inches.

A further object is to so construct and arrange the mechanism of thedevice that two registers of the work done shall be made. one of whichregisters shall be visible to and controllable by the operator and theother concealed from view and inaccessible to the operator whereby anytampering with the visible registering devices may be detected by thereadings of the concealed register.

With these and other objects in view. the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a view illustrating myimprovements. with the casing shown in section: Figure 2, is a viewtaken at right angles to Figure 1: Figure 3 is a sectional view on theline. 33 of Figure 2: Figure 4 is a view in section on the line 44 ofFigure 2. and Figure 5 is a View in section on the line 5 5 of Figure 2.i:

In describing the construction of my improved measuring device. I willassume by way of example that the sewing machine will make ten stitchesper inch of the g'OOds and that the needle shaft will make threerevolutions for each stitch.

A portion of the head of a sewing machine is indicated at l and thedriving or needle shaft 2 is provided with a gear 9 which may be securedeither to said shaft or to the fiy- 1 wheel 4;

A frame 5-is hinged at one edge to a plate 6 and the latter is adaptedto be secured upon the head 1 of the sewing machine. A

shaft 7 is suitably supported by the frame 5 and at one end. this shaftis provided with a gear 8 to mesh with the gear 9 and has three times asmany teeth as the latter so that the shaft 7 will make one revolutionfor each stitch. The shaft 7 is provided at its other end with a worm 10which meshes with a gear 11 on a shaft 12.said gear 11 having 10 teethso that it will make one revolution for each inch of stitching. Theshaft 12 is also provided with a worm 13 which meshes with a worm gear14 having twelve teeth so that it will make one revolution for each footof stitching. The gear 14 is carried by a shaft 15 and this shaft alsocarries a gear 16.

The shafts of disk registers Aand B are mounted in the frame 5 and theshafts of these registers carry gears 1718 respectively and arespaced.apart,a portion of the gear 16 being disposed between the gears17 and 18. A bifurcated carrier 19 is pivotally mounted in the frame 5and supports an elongated pinion 20 which may be made to mesh with thegears 16, 17 and 18 so that motion will be transmitted from the gear 16to both registers A and B simultaneously.

The register A may comprise four disks 0. 7), c. 07. The disk arepresents inches so that one revolution of this disk will'represent onefoot of stitching, this will be transferred to the disk 6 whichrepresents feet. The disk 6 is provided with a plurality of sets ofnumerals 0 1 2 and when this disk I shall have been operatedthree timesby the disk a, the disk 0 will be moved throug suitable transfer meansone point,the disk c thus being intended to indicate yards, and therotations of this disk 0 will, by suitable transfer means, operate thedisk 03 which is intended to represent tens of yards. The disks of theregister B have the same arrangement as the disks of the register A, butin the register B a greater number of disks may be employed (preferablysix) so that a greater aggregate number of yards of stitching may beregistered. The register B will be inclosed by a suitable cover B sothat it will be inaccessible to the operator, while the register A isvisible to the operator and capable of being set by him. The saidregister A maybe protected by a suitable covering havinga Window.

A shaft 21 is mounted in the frame and or disk 22 and after passingfreely through an opening in the bottom of the frame 5,

is pivotally attached to the base plate 6. A rod 25 is connected atone'end to the de-- pending portion of the pivoted carrier 19 and saidrod, after passing freely through a slot in the base of the frame 5,ispivotally attached to the base plate 6. -It will be observed that byturning the manually 0-perablc shaft 21 the frame 5 will be moved onits'hinged connection with the base plate 6 and the gear 8 will be movedout of mesh with the gear 9, thus disconnecting the de-- vice fromoperative relation to the needle shaft of the machine. It will also beobserved that when the frame 5 is thus tilted, the carrier 19 will beturned on its pivotal mountin and the elongated pinion 20 will be movedout of mesh with the gears 16, 17 and 18, thus rendering the registeringmechanisms inoperable.

'VVith the use of my improvements, duplicate registers of the number ofyards of stitching done by the sewing machine will be made, one ofsaidregisters being inaccessible by and out of view of the operator of thesewing machine so that should such operator tamper with the visibleregister, such tampering would be denoted by comparing the readings ofthe latter with the readings of the other register.

Having fully described my' invention what I claim as new and desire tosecure by Letters Patent, is: A

1. In a registering device, the combination of a frame, two similarregisters mounted therein, one of said registers being visible to theoperator and the other register being concealed from view of theoperator, means for actuating said registers simultaneously, and meansfor disconnecting the actuating means from said registers, whereby oneand only one of said registers maybe actuated independently.

2. In a device of the character described, the combination of a framemounted for swinging movement, similar registers mounted within' theframe, means whereby one of said registers is made visible and the othera concealed from view of the operator, a carrier pivotally mounted inthe casing adjacent the registers, a pinion mounted in said carrier andadapted to operate both registers, and means whereby swinging of theframe will cause the carrier to move the pinion to or fromthe registers.

3. In a device of'the character described, the combination of 'a base, aframe mounted on the base for vertical swinging move- 1nent, a registermounted in the frame, a carrier pivoted in the frame, a pinion on saidcarrier to actuate the register, and a rod extending through the bottomof the frame and pivoted at one end to the base and at its opposite endto the lower end of the carrier.

4. 111 a device of the character described, the combination of a base, aframe hinged at its rear side upon the base, a shaft mounted in theframe and operable from the exteriorthereof, a crank on said shaft, arod extending through the bottom of the frame and pivoted at one end tosaid crank and at its opposite end to the base, a register in-the frame,and a pinion'arranged to actuate the register and movable to or from thesame by the swinging of the frame.

In testimony whereof, I have signed this specification in the presenceof two sub scribing witnesses. i p SIDNEY LEE,
